User’s Guide
After you select a line representing a tieline (which you can do by clicking the line), the ‘Virtual
Levels’ sections become enabled. The upstream virtual levels section contain the virtual level
represented by the upstream partition of the tieline you selected. The downstream virtual levels
section contain the virtual level represented by the downstream partition of the tieline you
selected. You should check the check box next to the virtual level in both sections. (Alternatively,
you can check one or more of the entries in the ‘Signal Types’ sections.)
Checking the check box enables all the signal types assigned to that virtual level to become
selected (checked) in the ‘Signal Types’ section.
Signal Types
In these sections (both upstream and downstream) you can select the specific signal types that
the tieline will carry. The tieline will not be used for signal types not selected.
(Checking the virtual level check box in a ‘Virtual Level’ section enables all of the entries in the
corresponding ‘Signal Types’ section.)
Connection Graph
The ‘Graph’ section of the page is where you define the tieline’s cable connections.
When you have chosen an upstream physical level, the graph region shows a green rectangle
with numbered ports. The graph section will show more than one green rectangle if you have
selected more than one upstream partition.
When you have chosen a downstream physical level, the graph region shows a yellow rectangle
with numbered ports. The graph section will show more than one green rectangle if you have
selected more than one upstream partition.
The upstream partition may be the same as the downstream partition. Nevertheless, there will
be two rectangles.
(You might have to scroll to see the rectangles. You can move a rectangle with the graph region
by dragging.)
To create a tieline, draw a line from a port of a green rectangle to a port of a yellow rectange by
dragging your cursor from one port to the other. A line with an arrowhead appears. The line will
remain selected so that you can assign signal types to the line using the check boxes in the two
‘Signal Types’ sections of the page:
